   guia.css — Guías de fondo (proceso de compra, compra desde el exterior).
   Son páginas de texto largo, así que la tipografía y el ritmo de lectura
   mandan: medida de línea corta, jerarquía clara, índice fijo en escritorio.
   Mismo lenguaje visual que el resto del sitio (navy, oro, Fraunces/Manrope).
   Autónomo respecto a herramienta.css para no acoplar páginas distintas.
